Demonstrates EnterContext and LeaveContext using the Chilkat Log API.

Chilkat Ruby Downloads install from rubygems.org gem install chilkat or download... Ruby Library for Windows, MacOS, Linux, Alpine Linux

require 'chilkat'

log = Chilkat::CkLog.new()

# Initialize the log object with an initial context tag:
log.Clear("myLog")

# Add some information..
log.LogInfo("Hello, I'm here...")

# Open a sub-context
log.EnterContext("abc")

# New information is now logged within the "abc" context.
log.LogInfo("This is inside the abc context")
log.LogError("File not found.")

# Perhaps open a new context...
log.EnterContext("fileInfo")
log.LogData("filename","something.txt")
log.LogData("path","/somedir/xyz")
log.LeaveContext()

# Close the "abc" context.
log.LeaveContext()

# Examine the content of the log:
print log.lastErrorText() + "\n";

# This is the output:

# myLog:
#   Hello, I'm here...
#   abc:
#     This is inside the abc context
#     File not found.
#     fileInfo:
#       filename: something.txt
#       path: /somedir/xyz
#     --fileInfo
#   --abc
# --myLog
